Why not change the NFHS 10-second rule to match NCAA? Both sets of rules both start team control on the throw-in, so why not start the 10-second count on team control inbounds, rather than player control? This would render this entire discussion thread moot, as well as ease the inevitable transition to a high school shot clock.

Not correct. Team control in NFHS, for all but one purpose, starts with player control inbounds....the same time as the 10 count starts. College used to be the same. They changed to make the shot clock administration easier.
